*feR mme-N oHms." g I To all whmn itinay concern; I

Be it known that I, BENNETT D. MARKS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful which the following is a specification. j

My invention relates to that class of machines whereby the grain of the wood is transferred to a printing-cylinder and from. that to the wood. The use of machines of this kind has developed the fact that it is essential for their successful operation that means should be provided for a simultaneous adjustment of all the parts which engage'the The machines with Which- I. am familiar fail to provide this very necessary Specification of Letters Patent. Application filed January 30,1905. Serial 110. 243,203.

-. suitable power,

gear 15 which is mesh with a ing gear 16 mounted upon the shaft 14 and feature, and my invention has for its object this objection and to simplify the construction, make its action more positive,

tures more particularly pointed out hereinafter in the specification and claims.

My method .of accomplishing the foregoing may be more readily understood by having reference to the accompanying drawings, which are apart of this specification and are hereunto annexed, in which Figure 1 is a side elevation of my improved machine. Fig. 2 is a top or plan view of the same. Fig. 3 is a section taken on the lines X X in Fig. 1. Fig. 4 is a section taken on 2. Figs. 5, 6 and 7 are bearing box. Figs. 8 and 9 are enlargeddetails of a art of the'scra er. Figs. 1() and the roller adjust ment. Figs. 12 and 13 are enlarged details of the adjustment for the pan legs. Fig. '14 is a sectional view of the bevel gear. Fig. 15- is a detail of the small roller bearing. Fig. 16 is an enlarged detail View partly in elevation and partly in section.

Similar figures refer to similar parts throughout the entire description.

The machine is constructed as shown in the drawings of a frame 1 which is designed in two side framesZand 3 which are secured together by means of, stay-rods 4. 'T-. W0 shafts 5 extend along each side frame and are suitably jou'rnaled in boxes 6. These shafts, l which are mounted upon the uprights of the these teeth are engaged by .since the boxes 8 and 13 wardl- 'exten ing arm- 31 side frames, furnish mountings for boxes, 7

and 8 which furnish bearings for the shafts of the rollers 9 and 10. In machines of this de- My method of accomplishing thisis better ,e I Patentedmay 14, 1907- scription it is necessaryto regulatethe pres, sure with which shown in the detail views of the box 8, which has'an outwardly extending arm 12, froin which a box 13 extends at right angles to the said arm. The roller 10 is rotatedby means of a shaft 14,-which may be driven by any and has upon one side a bevel secured thereto by means of a pin .20 or some other form of fastening, and which is journaled. in the boxes 13 and 18. A gear 19,

is constructed with a' journal bearing 11 and correspondbetter shown in-Flg. 14', corresponding in size i to the gear 16 is slidable thereon. This gear is constructed With a hub which extends through the box 13 I and terminates in a collar 21, so that the movement of thebox will move the gear. A feather 36 is provided in said gear and slides in the slot 37 in the shaft 14. This gear is in mesh with a bevel gear 22 mounted-upon and secured to the roller .9. It is obvious thatare formed in one piece that the movement move the gear 19 With it and as a consee gear 22. A lug 17 extends from the end of the box and has pivotally attached thereto a link 23,'whose opposite end is secured by means of a in or pivot 24 to the end of the lever 25, W ch is fulcrumed upon. an outwardly extending lug 26 which extends from the end'of the side frame. A segment 27 is attached to the upper part face. As better seen in a pawl 29, which is mounted u on a rod 30 and has anupwhich is engaged by a at' spring 32 orfsome other convenient spring-actuated means.

splined upon this shaft and r p of the frame and has a number of teeth 28 out upon itsupper the detail views,

of the roller 9 will f qlnencekeep it in constant engagement with A similar construatlon ls-followed on the opposite side of the chine. and through the levers 25. of this construction would be that when it is desired to adjust frame, the rod 30 extending across the mai The result the friction existing beclutch tween the two rollers, by moving the rod outwardly the pawl will slide over the ratchet teeth 28 and through the medium of the lever, link and adjustment bearing boxes 5 will move the roller 9, and will move both sides of it at the same time with the utmost accuracy and niceness, and while the extended arm on the box 8 will keep the gear 19 in constant engagement with the bevel [0 gear 22 so that roller can be moved back and forward at will without taking it out of adjustment. This is especially desirable because after the machine has 0 erated all day it is necessary to clean the rol ers off which is 1. 5 done by putting benzin or some other paint remover into pans 33 and 37, which are mounted beneath each of the rollers. The rollers are rotated and the cleansing liquid is transferred to their surface through the me- I 2 o dium of a small roller 34 located in the end of the pan 33 and is scraped off of the surface of the rollers by-means of scrapers 35. A similar operation is followed re garding the other roller, which, however, it may be found tie-- 25 sirable to construct as a brush rather than a roller-in practice. These scrapers are con structed as better shown in the detail views of a rod 38 which extends across from the side frames 2 and 3 and is suitably journaled 3 in boxes 39 mdunted u on the lower crossbars of said fra'mes. Tl ie end 40 of this rod is bent at ri ht angles thereto andextends ,along the sife (if the frame as indicated by the dottedlines in Fig. 1. A scraper 41 formed of leather or some other suitable material is mounted in a slot milled into the rod 38 and is reinforced or stiffened bya strip ofmetal 42 which is attached thereto by means of rivets 43 or any other suitable method of fastening. The end of the upwardly extend-- in arm 40 is engaged by the lower end 44 of a ever 45. This. end 44 is formed eccentrically so that the movement of the handle on the opposite end of the lever 45 will cause -bear firmly against the face of the rollers.

.the lever to any position Wished, it being held in lace by means of a segment and f ordinary construction. A similar method is carried out as regards the scraper for the other roller.

The two levers 45 may be connected as inshould exert a constant and even pressure against the surface of the-roller in order to transfer the paint or rinting mixture evenly. This is'aceomplished as better shown in Fig. 15,- which is an enlarged detail view ofthe box which forms a bearing for the ends of the 6 5 roller. This box is formed of twp halves 47 the foot 44 to press down upon the arm 40,- thereby raising the scraper and causing it to dicated by-the dotted lines, by lever connec'-' and 48, which are slidable in a roove in the two upright portions 49, the enr of the roller 34 resting in a journal bearin formed in the center of the lower half of the ox 48. A coil slpringl 50 is mounted in an openin formed lrect y beneath the end of the sha t 34 and the lower end of this spring bears on the face of an inclined wedge 51, the result being that there is a constant pressure against the shaft of the roller and as a result against the face of the large roller. This tension may be regulated by means of a screw 52 which is threaded into the inclined Wedge 51 so that by turning it the wedge is advanced and the tension of the spring is'correspondingly increased,v thus insurin a constantand even friction between theace of the two rollers.

The pans 33 and 37 are mounted upon legs 53'which are adjustable, so that it is possible to easily and quickly raise or lower the pans either for the purpose'of removing them or to 7 keep the liquid in the end where the roller or brush is located. The method of adjustment is more clearly shown in the detail views, Flgs. 13 and 13, Fig. 12 being an elevation partly 1 n section. Fig. 13 is a to or plan view with a part of the side wa s broken away to show the bearing of the clamp, The

.leg 53 is provided with a foot 55 to insure steadiness Attached to the side of the pans 1s a box or trap having two side walls 56 and 57. These walls are riveted or bolted to the sides of the pan and have journaled in themselves two plates 58 and 59. These plates are formed with openings 60 which are of slightly larger diameter than the leg 53. A coil spring 61 is located around the leg 53 and intermediate to the plates '58 and 59; the result belng that the spring, tending to expand, spreads thc two plates and causes the edges of the openings 60 to engage the leg 53 and clamp it securely; When it is desired to raise or lower the leg, by squeezing the plates together and compressing the spring it be comes possible to move the leg up and down at the will of the o erator and being released it will automatica y clamp and hold itself in the position desired. r

In a machine of this character; it has been found extremely diflicult to construct a roller from which the grain is to be transferred which would not get out oftrue and as a con- V segluence warp ,or crack. I overcome this di culty,.bythe improvedconstruction of my roller, which is more clearlyseen in Fig. 4 and for which I have filed an application forLe'tters Patent of the United States.- This roller is formed of a series ofboards 62 which are ta ered and fitted in radially around the hub, in which is fastened the'shaft of the roller 8. This construction op oses" a perofthe roller, so that as it reaches or nears the st. Tk sea peas tweet it straage e of t ese boards is then turned true and a covering 63, which is preferably formed ofhard rubber althou'gh some other material may'be'found as desirable in practice is "formed or molded around thefedge of the roller.- Ihis surface being turned leaves a n' perfect surface to which to secure the-wood to m which the gram is to betransferre'd 165, the result being that when this construction is followed a practically true roller is made which will maintain its even surface under any and all conditions. I

' In machines of hischaracter it-is very desirable to have the'roller to which the-grain of the wood is transferred of such construction as to permit it to be used not only in of material desired without ject matter of an application for Letters P-atent'of the United States is more clearly illus-' trated in Figs.v 3 and 4,'in which 66 is a spool orc'ore which s formed in the usual manner with flanges 67 and 68; A layer of spongy substance, both elastic and compressible, preferably sponge rubber, ,69 is formed or molded around the core 66, The. thickness of this substance should be regulated to adapt-itselfto the size of the. molding or irregular-surfaces which it is desired to grain. A composition 70 formed of glue and molasses, or some. equivalent composition, is :then .molded around the sponge rubber 69.

-The result of this construction is obvious.

' When a molding is fed into the machine the composition will conform to the lines offered 'by the face of the molding, it being permitted to yieldb'y the spongy substance and as soon as. the molding is passed through, the spongy material, due, to itsresilience, will cause the roller to resume its natural and regular surface.

in the side frames 2 and 3, are a aptedQ to carry the material .which is to be printed to the face.of the roller. 10. A roller 72 is provided to hold the material in engagement fss' with the face of the roller 10, said roller being journaledlinbearings 73 which are slid- 'a'ble 1n guide's 74-mounted upon the side --frames 2 and 3.- I mount a sprocket Wheel P n th upper end of a'screw 76 which is Rollers? 1, the ends of which are, "ourn'aled mover is placed in the pan'37. The wheels are then rotated and through the medium of the roller 34 the paint is transferred, to the face of the roller 9, the surplus'being scraped off by the scraper 41, leaving the pores of the grain filled with aint. This is transferred rollers '71. These rollers may be rovided of the material to'be printed, The material isrheldi in engagement with the face of the roller 10 throughthe medium of the roller 72.

-. In machines with whichI am familiar, it has been practically impossible to ad'ust .this "roller so as to cause it to exert an a solutely of the wood is transferred ei eronly to: one side or the other, or in some instances will press so hard as tohlur the grain and thereby spoil the im ression. This objection is ut terly avoide by my construction, since the s rocket wheels, being provided with. the c ain 7 7, necessarily move .inperfect unison. The result is obvious that the rotation ,of the quence the roller 72 is raised or lowered perfectly even and as a consequence exerts an even pressure upon the material, the result being. that it becomes possible to secure a perfectimpression through operation. Have ing transferred the impression, the face, of the 37 and scrapedoff by the roller, thus presenting a new clean surface to receive'the impression from the graining roller.
